OHBM 2026: Sound and Music — when two people enter the same rhythm, do they think better together?

OHBM 2026 brings a particularly fertile theme for anyone who wants to think about neuroscience in a more alive and embodied way: Sound and Music: Naturalistic Approaches to Auditory–Motor and Affective Brain Dynamics. In addition, the oral program includes the topic Naturalistic fMRI and Instrument-Specific Neural Synchronization in Musicians. That combination alone already signals an important shift: music is not being treated only as a sound stimulus or as individual performance, but as an auditory-motor, affective, and relational dynamic. Music appears, then, as a living laboratory for thinking about coordination, body, emotion, and belonging.

This has major value for a Decolonial Neuroscience reading. For a long time, science risked studying cognition in environments that were too still, too silent, and too abstract. But real human life rarely works like that. We live in rhythms, in encounters, in pauses, in shared breathing, in collective timing. Music makes this especially visible: it shows that thinking, feeling, and acting together may not be separate things at all.

In Brain Bee language, the question can become:

Could playing, tapping rhythm, or singing together help the brain cooperate better?

This is a strong question because it brings neuroscience closer to lived experience. Teenagers understand this immediately. Everyone has felt the difference between being “in the same rhythm” with someone and being out of phase. Sometimes this happens in music. Sometimes in conversation. Sometimes in a classroom. Sometimes in a group that finds a shared pulse and becomes able to create together. The point of OHBM 2026 is that this now appears more clearly in the scientific agenda itself, as the congress brings together Sound and Music, Naturalistic Approaches, and Neural Synchronization in Musicians.

Here, the avatars that help most are APUS and Jiwasa.

APUS matters because music is never only sound entering the brain. Music is also body in space, time, gesture, breathing, posture, fine-tuned movement, and presence in the environment. When two people enter the same rhythm, it is not only the ear that takes part. The whole body enters the experience.

Jiwasa matters because shared rhythm is a powerful form of “we.” It helps us think about synchrony, cooperation, and belonging without reducing everything to isolated individuals. Sometimes a group thinks better because it enters a common pulse. Sometimes a group merely repeats better. Music is an excellent field for separating one from the other.

The decolonial critique here can be simple: much theory still treats cognition as if the brain produces intelligence alone, and only afterward connects to the world. But when OHBM 2026 brings themes such as Naturalistic Approaches to Auditory–Motor and Affective Brain Dynamics and Naturalistic fMRI and Instrument-Specific Neural Synchronization in Musicians, it suggests almost the opposite: there are forms of intelligence that emerge through the encounter between body, environment, time, and coordination.

A better question, then, would be this:

What changes in attention, regulation, and sense of collectivity when two people enter the same rhythm?

That is a good question for OHBM 2026, a good question for Brain Bee, and a very important question for Latin America. In our region, music has never been a minor detail. It crosses celebration, ritual, street life, school, religion, protest, memory, and identity. Thinking about music as a laboratory of belonging is a serious way to expand neuroscience without losing rigor.

A Brain Bee proposal for an EEG + NIRS experiment

The proposal can be simple and powerful: compare pairs in a rhythmic synchrony condition with pairs in a desynchronization condition, using clapping, finger tapping, light percussion, or short vocal patterns. With EEG, we can observe coherence and synchrony between participants. With NIRS, we can track frontal responses related to adjustment, error, and joint effort.

The goal would not be to discover who “performed better,” but to observe how brain and body change when shared rhythm facilitates — or disrupts — cooperation. The central hypothesis is direct: entering the same rhythm may reorganize attention, error processing, and coordination in ways that differ from isolated tasks.

Where OHBM 2026 is already pointing in this direction

This blog grows directly out of the official program. The symposium Sound and Music: Naturalistic Approaches to Auditory–Motor and Affective Brain Dynamics is scheduled in the congress, and the Higher Cognitive Functions session includes the topic Naturalistic fMRI and Instrument-Specific Neural Synchronization in Musicians. This shifts the question.

Instead of asking only “which brain area responds to music?”, the discussion can become richer: how does shared rhythm reorganize coordination, emotion, synchrony, and meaning-making between people?

Why this matters for Latin America

In our region, music and rhythm are deeply embedded in collective life. They are not only entertainment. They are also language, memory, bonding, resistance, celebration, and ways of inhabiting the body. That is why a neuroscience built from here gains a great deal when it stops treating music only as an acoustic stimulus and starts seeing it as a living organization of belonging.

This is especially important for young people between 14 and 17 years old. They quickly perceive when a group enters synchrony and when it does not. If Brain Bee Latam wants to inspire new scientific questions, music is one of the most beautiful and accessible paths.

The beauty of this OHBM 2026 theme is exactly this: it already opens space to move beyond the isolated brain and toward the brain in relation.

Instead of asking only how the brain hears music, we can ask:

What changes when two people tap the same rhythm?
When does synchrony help cooperation, and when does it only generate repetition?
How do sound, body, and bond reorganize attention and shared effort?

When neuroscience begins to measure that, it stops being only a science of hearing and starts becoming also a science of lived rhythmic encounter.
